Epbf

This article provides guide to the different developer tools available for writing eBPF programs, covering the core tools BCC, bpftrace, ebpf-go, and libbpf. These tools satisfy a different use case depending on whether you are trying to use eBPF for running analysis scripts, or full-fledged programs, in what programming language you wish to use, and the maturity and feature parity with the most recent eBPF features in the Linux kernel. Unfortunately, there is no single definitive guide to BPF and there is still a lot of unwritten knowledge, though some of the resources provided in this article may help you get started on your own journey. ...

A short tagline from the book Learning eBPF describes eBPF as a revolutionary kernel technology that allows developers to write custom code that can be loaded into the kernel dynamically, changing the way the kernel behaves. The key word in this phrase is dynamically. eBPF allows you to write custom code that changes the way the kernel behaves without having to implement a kernel module or integrate your code directly into the kernel. ...
